"Second Lieutenant (temporary Captain) William Douglas Stock Sanday, Royal Flying Corps, Special Reserve.
For conspicuous gallantry and skill near Hulluch on 1st January, 1916.
He went out in a very high wind to observe the fire of a battery, and, owing to the clouds, was forced to fly at a height of between 800 and 900 feet. Although continually subjected to very heavy rifle fire from the German trenches, he enabled our battery to obtain several direct hits."
